Fig. 2From: Association between low hemoglobin, clinical measures, and patient-reported outcomes in patients with rheumatoid arthritis: results from post hoc analyses of three phase III trials of sarilumabRelationship between Hb levels and clinical efficacy outcomes: PtGA and pain VAS over time. Slicefit plots of PtGA (MM) and pain VAS (MM) (Y-axis) against hemoglobin (g/L) (X-axis) by a visit from baseline to week 24. Each panel in the regression model shows the relationship between an outcome and Hb level at a given point in time, stratified by treatment. The lines, with shading, depict the treatment-specific regression coefficient (i.e., slope) and 95% CI associated with the linear regression in which Hb is the independent variable and the outcome is the dependent variable.
